Editor Plugins

Reason 的天性給編輯器有極大的支援。大多數編輯器外掛,至少提供了:

  • 型別顯示。
  • 透過 refmt 自動編排程式碼。
  • 錯誤 & 警告顯示。
  • 語法高亮顯示。
  • 型別驅動自動補完。
  • 跳至定義。

以及其他功能。

Editor Plugins & Language Server

Since Reason is just an alternative syntax for OCaml, we integrate seamlessly into the official OCaml editor toolchain as well.

  • For VSCode, we recommend using the vscode-ocaml-platform plugin, which offers OCaml & Reason support out of the box.
  • For other editors, we recommend using a language server client plugin of your choice, and pairing it with the ocaml-lsp. Check out the respective README's to get started.

Other:

  • Vim/Neovim: Make sure to use ocaml-language-server for native development as suggested. (Mac, Linux): npm install -g ocaml-language-server
  • vim-reasonml: For use with esy, Reason, and Merlin (not LSP based). (Mac, Linux, Windows).
